docker - 如何处理VSCode Remote dev容器中的多个 `network_mode`？

Question

我希望在开发容器中运行一个应用程序、数据库和 redis 服务，我可以在容器、应用程序和 Windows 上访问我的数据库和 redis，这就是我目前想要的对于我的应用程序和数据库:

.devcontainer.json:

{
  "name": "Node.js, TypeScript, PostgreSQL & Redis",
  "dockerComposeFile": "docker-compose.yml",
  "service": "akira",
  "workspaceFolder": "/workspace",
  "settings": {
    "typescript.tsdk": "node_modules/typescript/lib",
    "sqltools.connections": [
      {
        "name": "Container database",
        "driver": "PostgreSQL",
        "previewLimit": 50,
        "server": "database",
        "port": 5432,
        "database": "akira",
        "username": "ailuropoda",
        "password": "melanoleuca"
      }
    ],
    "editor.formatOnSave": true,
    "editor.codeActionsOnSave": {
      "source.fixAll": true
    }
  },
  "extensions": [
    "aaron-bond.better-comments",
    "dbaeumer.vscode-eslint",
    "esbenp.prettier-vscode",
    "mtxr.sqltools",
    "mtxr.sqltools-driver-pg",
    "redhat.vscode-yaml"
  ],
  "forwardPorts": [5432],
  "postCreateCommand": "npm install",
  "remoteUser": "node"
}

docker-compose.yml:

version: "3.8"

services:
  akira:
    build:
      context: .
      dockerfile: Dockerfile
    command: sleep infinity
    env_file: .env
    volumes:
      - ..:/workspace:cached

  database:
    image: postgres:latest
    restart: unless-stopped
    environment:
      POSTGRES_USER: ailuropoda
      POSTGRES_DB: akira
      POSTGRES_PASSWORD: melanoleuca
    ports:
      - 5432:5432
    volumes:
      - pgdata:/var/lib/postgresql/data

  redis:
    image: redis:alpine
    tty: true
    ports:
      - 6379:6379

volumes:
  pgdata:

Dockerfile:

ARG VARIANT="16-bullseye"
FROM mcr.microsoft.com/vscode/devcontainers/typescript-node:0-${VARIANT}

如您所见，我已经尝试使用 networks 实现我想要的，但没有成功，我的问题是:如何将 Redis 添加到我的服务中，同时仍然能够连接 redis 和数据库在应用程序内部和 Windows 上？

将所有非开发容器切换到network_mode: service:akira

version: '3.8'
services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - ../..:/workspace:cached
    command: sleep infinity
  postgresql:
    image: postgres:14.1
    network_mode: service:akira
    restart: unless-stopped
    volumes:
      - ../docker/volumes/postgresql:/var/lib/postgresql/data
    environment:
      POSTGRES_PASSWORD: postgres
      POSTGRES_USER: postgres
      POSTGRES_DB: pornapp
  redis:
    image: redis
    network_mode: service:akira
    restart: unless-stopped
    volumes:
      - ../docker/volumes/redis:/data

这似乎是原始配置: https://github.com/microsoft/vscode-dev-containers/pull/523

但它被恢复了，因为如果你在其他服务运行时重建开发容器，端口转发将会中断: https://github.com/microsoft/vscode-dev-containers/issues/537
